Features
▶ Fixed motor with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in open and closed circuits
▶ For use in mobile and stationary applications
▶ Design with SAE mounting flange and UNF resp. UNCthreads
▶ Also available as plug-in version and with metric threads
▶ The output speed is dependent on the flow of the pump and the displacement of the motor.
▶ The output torque increases with the pressure differential between the high-pressure side and the low-pressure side.
▶ Finely graduated sizes permit far-reaching adaptation to the drive concerned
▶ High power density
▶ Small dimensions ‒ compact design
▶ High total efficiency
▶ Good starting efficiency
▶ Integrated flushing valve optional
